期望脚本错误发送：Spawn id exp4在执行时未打开

我试图运行这个脚本，但修改时有不同的错误。 这里是代码和输出。 请帮忙。

在post结尾更新debugging信息

#!/bin/bash (( $# != 1 )) && { echo >&2 "Usage: $0 \"[COMMAND]\""; exit 1; } servers_addresses=(10.10.10.10 ) for server_address in ${servers_addresses[@]}; do expect <<EOF spawn ssh -t root@$server_address "$*" expect -timeout 2 "Are you sure you want to continue connecting (yes/no)?" { send "yes\n" } expect "s password:" { send "Correct_Password\n" } expect "s password:" { send "Wrong_Password_22222\n" } expect "s password:" { send "Wrong_Password_33333\n" } expect eof EOF done 

输出如下所示：

  goldberg188@Test-Server ~$ ./test.sh "sudo cat /etc/hosts" spawn ssh -t root@10.10.10.10 sudo cat /etc/hosts root@10.10.10.10's password: # Do not remove the following line, or various programs # that require network functionality will fail. 10.10.10.10 TEST-004 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 Connection to 10.10.10.10 closed. expect: spawn id exp4 not open while executing "expect "s password:" { send "Wrong_Password_33333\n" }" 

如果我这样修改，那么输出会有点不同

• 获取输出为pipe道的命令的pid
• 如何使用sed和awk的find命令从文件中删除重复的IP
• 将parameter passing给Python subprocess.Popen
• 如何在Django开发服务器运行时使用unix命令？ （图片提供）
• 如何检查前一次运行是否失败？

  expect "s password:" { send "Wrong_Password_11111\n" } expect "s password:" { send "Correct_Password\n" } expect "s password:" { send "Wrong_Password_33333\n" } goldberg188@Test-Server ~$ ./test.sh "sudo cat /etc/hosts" spawn ssh -t root@10.10.10.10 sudo cat /etc/hosts root@10.10.10.10's password: # Do not remove the following line, or various programs # that require network functionality will fail. 10.10.10.10 TEST-004 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 Connection to 10.10.10.10 closed. expect: spawn id exp4 not open while executing "expect eof" 

如果第三行的密码正确，那么根本就没有错误。 在这一个工作很好。

  expect "s password:" { send "Wrong_Password_11111\n" } expect "s password:" { send "Wrong_Password_22222\n" } expect "s password:" { send "Correct_Password\n" } goldberg188@Test-Server ~$ ./test.sh "sudo cat /etc/hosts" spawn ssh -t root@10.10.10.10 sudo cat /etc/hosts root@10.10.10.10's password: # Do not remove the following line, or various programs # that require network functionality will fail. 10.10.10.10 TEST-004 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 Connection to 10.10.10.10 closed. 

更新：debugging信息 – 修改为

  exp_internal 1 expect "s password:" { send "Wrong_Password_11111\n" } expect "s password:" { send "Correct_Password\n" } expect "s password:" { send "Wrong_Password_33333\n" } 

输出：

  spawn ssh -t root@$server_address "$*"
